clutch:Single chip dry film spring clutch, vibration spring and friction damping tablets, friction outer diameter 4) 350 mm, hydraulic length distance manipulation, booster, suspension pedal.
Gearbox:Mechanical drive transmission. Five forward gears and reverse, two to five gears, with locking inertial synchronizers, have a tibiedate patch gear. Center distance: 135mm. Each speed ratio is: i1= 6.602, I2= 3.743, I3= 2.13, I4= 1.297 I.5= 1.000, Ir= 6.705.
Transfer case:Mechanical, high low, two gears, front axles can be bonded or separated, engaged in output shafts. The manipulation method is long distance electric control, longitudinal ratio IH= 1.348 low speed ratio IL= 2.41
TAILBOX:Machinery, mounted on the right side of the transmission. A reverse, the maximum output power is 22.05 kW. Rate ratio: item 1.518, reverse 1.012.
slope:Put it in the rear of the vehicle, the engageable sleeve in the manipulator is connected to the engagement drum, the steel wire is 13mm, the maximum working tension 44100N, and the working length is 50m.
Steering device:釆用 HFB52 single-piece power steering gear, the intermediate position transmission ratio is 20.4.
brake:The parking brake is powered by the air shutoff spring, mounted in the rear of Transfer case, and is implemented by manual control valve to control the spring gas chamber. The brake line is used to use a nylon hose, and the engine exhaust operation is an auxiliary brake. Early production vehicle trailer brake is a dual tube inflator, in order to match the match, the trailer brake of the vehicle is complex in two inflation braking and ventilation.
shelf:The maximum portion of TAP is 232x75x6.5mm. The outer shape of the front bumper is considered to increase the relationship between the cab's positioning, and the cab has increased the mushroom device and avant-garde.
taxi:flat head Double-column cable mechanism is used in combination with Japanese products. The maximum flip angle is 45.
fetal:tyre uses 12.5R20 Meridian diamond block integrated pattern plus tyre, the fetal width is 350 mm, and the load capacity and power of the vehicle are improved. At the same time, the tyre The pattern is not symmetrical, with better integrated driving performance.
Wheel network:9.0V-20.
tyre air pressure:When off-road travel, the air pressure is 350 kPa, and the load capacity is 2000kg.
When driving, the air pressure is 450 kPa, ie 2200kg.
When running in a short time, tyre Air pressure can be adjusted to 180kpa
electronic system:new design
24 volts, single poles, negative iron
Battery: 12V. M 2 (low temperature)
Starter: 24V, 4.5KW, tooth 10 teeth
Cold boot device:In order to satisfy the car in a low temperature environment, the car is equipped with a PTC hot ceramic intake preheating device, which can be successfully started - 40 ° C; heating jacket remains on the engine. . Using a plug wire in a car, you can use an external power supply to heat the coolant and oil synchronous battery heating incubator.
